To all'wlwm it may concern:

Be it known that I, SAMUEL H. Penman, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Compositions for Treating aper, of which the following is a specification.

The present invention is in the nature of an improvement on a somewhat similar composition described and claimed by me in my application No. 302,219, filed June 6, 1919. In said application was described a solution of fir balsam, turpentine and Carbona (or carbon tetrachlorid) forthe purpose of impregnatin paper in order to make it transparent; The composition there described has been very successful for the purpose in view, but has a tendency to leave the pa r after it becomes dry in a slightly inflexi le condition and inchned toward brittleness. It is an object of the present invention to provide a similar composition which, when applied to paper, will make it equally transparent and at the same time leave it tough and flexible and of permanent transparency.

My improved composition has the further advantage that papers treated therewith do not alter, darken or change color for long periods of time as ascertained by actual trial but maintain -their original appearance, transparency and color. When moderately dry and at ordinary temperatures, the paper to which my improved composition has been applied, is not sticky and may be freely handled or brought into close contact with other sheets of the same material or other materials without stickingzf When moistened and slightly warmed however, paper treated with my improved composition will firmly adhere to smooth surfaces to which it 19 applied with pressure and it will continue to adhere after it is cooled and dried out. It is, furthermore, substantially water-proof and the above described characteristics adapt it for use in advertising matter and the like, to be applied to show windows, show cases, etc., in the form of letters, figures and the like.

My improved composition consists of the well-known soya bean oil, Carbona (carbon tetrachlorid) turpentine and fir balsam. The precise proportions of these materials depend upon the particular qualities most desired in the paper, to which they are applied. If great flexibility and toughness are re uired, more of the so a bean oil and rbona are used, but i less flexibility is desired and any considerable adhesiveness is to be avoided, more fir balsam and turpentine are used. A preferred formula for my composition is asfollows:

. Parts. Soya bean oil I 1 Tetrachlorid of carbon 3 Turpentine 4 Fir balsam 8 For the best results the bean oil and Carbona are thoroughly stirred together and the balsam and turpentine are likewise stirred together and then the two solutions so formed are well mixed to ether. The liquid is then ready to be applied. In case the liquid is to be used for the production of lettering on show windows or the like, the material is applied to paper which is so impregnated or covered with opaquecoloring matter that the application of the composition does not render it translucent. The required letters are then cut out of the aper and are moistened and slightly heate and a plied to the glass with a pressure sufliciently firm to press outany air from between the glass and the paper. It is suificient then to let the letters cool down and dry out and they are thus permanently attached to the glass. If gilt lettering is desired it is sometimes preferable to cut out the letters from gilt paper or the like and apply an overlapping backing of aper to which my improved com sition as been applied so that when the etter is moistened and slightly heated and applied to the glass the margins of the backing overlap the gilt and adhere to the glass. The gi t is thus well protected from the air and will not tarnish.
